5. System Wiring

All AS ampli ers are multichannel, i.e. each output channel (speaker) has an independent input connector, which is the perfect solution to
manage different acoustic areas or to create environmental music with different sounds.
Input Connection >
repeated using the Link outputs; by connecting with a RCA-RCA cable Link_1 to Input_2 it repeats the same source to speakers 1 and 2.
Output Connection >
speakON NL4 series plugs.
Each cable conductor must have the minimum cross section shown on the following table.
The cables must be of adequate quality, with a exible insulation, suitable for the installation's environmental conditions, and with suf cient
copper section to minimize power loss.
Cable lenght
ATTENTION: the output's connectors screw terminals and the output cables may be at a dangerous voltage value.
Make all wiring with the ampli er switched off.
Wire the output cables before plugging the connectors to the ampli er.
Complete the speakON plugs' assembly, installing the protective sleeve, before plugging them in the ampli er's sockets.
Never leave any output conductor un-insulated or accessible to the hand.
ATTENTION: the ampli ers are BTL (bridged) type.
The output socket's negative terminals are not connected to ground and it does not exist any common terminal in the outputs
(both negative or positive).
DO NOT CONNECT any output terminal to any other: doing this may result in a failure of the power ampli er's output stages.
NOTE: all the following drawings refers to a Neutrik
manufacturer's connectors may have s slightly different aspect, so always refer to the pin numbers printed on the
connector's body.
The connection of the music source to the ampli er is via RCA connectors (Input). The same source can be
RCA connectors
Use screened cables,
1 conductor + screen, wired to RCA pins.
For a simpler approach, we recommend using 2-conductor or 4-conductor cables wired to Neutrik
